Abstract
Due to varying thermal cycles, the resulting microstructure of metal additive manufacturing differs from the conventionally processed counterpart alloys. Since the mechanical properties depend on the microstructure, the wear resistance of components manufactured by laser powder bed fusion (LPBF) is determined by the processing parameters. This work focuses on microhardness and sliding wear of 316L stainless steel, evaluated nanoindentation and pin-on-disc, respectively, analysed through optical microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and glow discharge emission spectrometry (GDOES). The results show that the LPBF-processed specimens have about 40% higher microhardness and ca. 30% lower wear rate than the wrought counterpart. The enhanced sliding wear resistance is associated with the higher density of dislocations at the cellular subgrain boundaries.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
